ABSTRACT:
Curable epoxy resin compositions are described which comprise a mixture of an acid curable epoxy resin and a minor amount of an oxidizing agent capable of reacting with sulfur dioxide to form a catalyst for curing said epoxy resin. The curable epoxy resin composition may contain solid particulate materials. The procedures for curing such epoxy resins as well as methods for forming sand cores and molds also are described. Sand cores and molds produced in accordance with the method of the invention have sufficient strength and hardness after a few seconds of curing for normal foundry applications.
